Baseline [18F]FDG PET/CT and MRI first-order breast tumor features do not improve pathological complete response prediction to neoadjuvant chemotherapy.

PURPOSE: To verify the ability of pretreatment [18F]FDG PET/CT and T1-weighed dynamic contrast-enhanced MRI to predict pathological complete response (pCR) after neoadjuvant chemotherapy (NAC) in breast cancer (BC) patients. METHODS: This retrospective study includes patients with BC of no special type submitted to baseline [18F]FDG PET/CT, NAC and surgery. [18F]FDG PET-based features reflecting intensity and heterogeneity of tracer uptake were extracted from the primary BC and suspicious axillary lymph nodes (ALN), for comparative analysis related to NAC response (pCR vs. non-pCR). Multivariate logistic regression was performed for response prediction combining the breast tumor-extracted PET-based features and clinicopathological features. A subanalysis was performed in a patients' subsample by adding breast tumor-extracted first-order MRI-based features to the multivariate logistic regression. RESULTS: A total of 170 tumors from 168 patients were included. pCR was observed in 60/170 tumors (20/107 luminal B-like, 25/45 triple-negative and 15/18 HER2-enriched surrogate molecular subtypes). Higher intensity and higher heterogeneity of [18F]FDG uptake in the primary BC were associated with NAC response in HER2-negative tumors (immunohistochemistry score 0, 1 + or 2 + non-amplified by in situ hybridization). Also, higher intensity of tracer uptake was observed in ALN in the pCR group among HER2-negative tumors. No [18F]FDG PET-based features were associated with pCR in the other subgroup analyses. A subsample of 103 tumors was also submitted to extraction of MRI-based features. When combined with clinicopathological features, neither [18F]FDG PET nor MRI-based features had additional value for pCR prediction. The only significant predictors were estrogen receptor status, HER2 expression and grade. CONCLUSION: Pretreatment [18F]FDG PET-based features from primary BC and ALN are not associated with response to NAC, except in HER2-negative tumors. As compared with pathological features, no breast tumor-extracted PET or MRI-based feature improved response prediction.

Microenvironment-induced restoration of cohesive growth associated with focal activation of P-cadherin expression in lobular breast carcinoma metastatic to the colon.

Invasive lobular carcinoma (ILC) is a special breast cancer type characterized by noncohesive growth and E-cadherin loss. Focal activation of P-cadherin expression in tumor cells that are deficient for E-cadherin occurs in a subset of ILCs. Switching from an E-cadherin deficient to P-cadherin proficient status (EPS) partially restores cell-cell adhesion leading to the formation of cohesive tubular elements. It is unknown what conditions control EPS. Here, we report on EPS in ILC metastases in the large bowel. We reviewed endoscopic colon biopsies and colectomy specimens from a 52-year-old female (index patient) and of 18 additional patients (reference series) diagnosed with metastatic ILC in the colon. EPS was assessed by immunohistochemistry for E-cadherin and P-cadherin. CDH1/E-cadherin mutations were determined by next-generation sequencing. The index patient's colectomy showed transmural metastatic ILC harboring a CDH1/E-cadherin p.Q610* mutation. ILC cells displayed different growth patterns in different anatomic layers of the colon wall. In the tunica muscularis propria and the tela submucosa, ILC cells featured noncohesive growth and were E-cadherin-negative and P-cadherin-negative. However, ILC cells invading the mucosa formed cohesive tubular elements in the intercryptal stroma of the lamina propria mucosae. Inter-cryptal ILC cells switched to a P-cadherin-positive phenotype in this microenvironmental niche. In the reference series, colon mucosa infiltration was evident in 13 of 18 patients, one of which showed intercryptal EPS and conversion to cohesive growth as described in the index patient. The large bowel is a common metastatic site in ILC. In endoscopic colon biopsies, the typical noncohesive growth of ILC may be concealed by microenvironment-induced EPS and conversion to cohesive growth.

Programmed death-ligand 1 (PD-L1) expression in cervical intraepithelial neoplasia and cervical squamous cell carcinoma of HIV-infected and non-infected patients.

Programmed death-ligand 1 (PD-L1) is overexpressed in cervical carcinoma, hindering tumor destruction. The aim of this study was to assess PD-L1 expression by immunohistochemistry in cervical squamous cell carcinoma (SCC) and squamous intraepithelial lesions (SILs) from human immunodeficiency virus-positive (HIV+) and human immunodeficiency virus-negative (HIV-) patients. A total of 166 SCC and SIL samples of HIV+ and HIV- patients were included and analyzed for PD-L1 expression through tumor proportion score (TPS), and results were stratified in five TPS groups using SP263 antibody and, combined positive score (CPS) using 22C3 antibody. In cohort 1 (SP263 clone), all HIV+ patients were negative for intraepithelial lesion or malignancy (NILM), and low-grade squamous intraepithelial lesions (LSILs) scored < 1; and 87.5% of high-grade squamous intraepithelial lesions (HSILs) adjacent to SCC, 19% of HSILs non-adjacent to SCC, and 69% of SCCs scored ≥ 1 (15.4% scored 5). In HIV- patients, all NILM, LSILs, HSILs adjacent to SCC, and two HSILs non-adjacent to SCC scored < 1. SCC: 88.2% scored ≥ 1 and 5.9% scored 5. In cohort 2 (SP263 and 22C3 clones), 16.7% of HIV+ patients with SCC were positive with both clones, CPS ≥ 1 (22C3) or score 5 (≥ 50%) (SP263), showing no significant differences in positivity between both clones. These results indicate that a relatively low percentage of SCCs (16.7%; both in HIV+ and in HIV- patients) express PD-L1 (TPS ≥ 50% and CPS > 1), which may be due to some samples being archival material, sample characteristics, or use of different methodologies, highlighting the need for standardization of PD-L1 assessment in SCC of the cervix. The fact that PD-L1 is overexpressed in SILs of HIV+ patients suggests potential additional applications for immunotherapy in this disease.

Nurse managers' ethical problems in hospital settings: an analysis from the macintyrian perspective / Problemas éticos de las enfermeras gestoras en el contexto hospitalario: un análisis desde la perspectiva macintyriana / Problemas éticos de enfermeiras gestoras no contexto hospitalar: uma análise na perspectiva macintyriana

ABSTRACT Objective: to understand hospital nurse managers' ethical problems from the perspective of Macintyre's virtue ethics. Method: qualitative research of the single case study type, encompassed by Alasdair Macintyre's theoretical framework of virtue ethics. Sixteen nurses in management positions participated in the study for a minimum period of six months. The setting was a university hospital in Belo Horizonte, Brazil. Data were collected between August and October 2021, through individual interviews with a semi-structured script and document analysis, analyzed using Bardin's content analysis. Two categories of ethical problems emerged from the thematic analysis linked to violations of care values: internal goods; and linked to breaking norms, patterns of behavior and interpersonal relationships: external goods. Results: the ethical problem is present in care, in relationships and in the institution. When referring to the profession's internal assets, ethical problems are characterized as a violation of care values: denial of assistance, negligent and reckless actions or violation of the rights of professionals, patients, staff and institutions. When referring to external goods, such problems are linked to interruption of norms, inappropriate actions and behaviors or ethical conduct questioned and disrespected by professionals. Conclusion: nurse managers understand ethical problems as circumstances that generate opposition to actions considered correct and that go against what is proper to nurses and against their duty, negatively affecting professionals, patient care, the institution and the public service.

RESUMEN Objetivo: comprender los problemas éticos de las enfermeras gestoras hospitalarias desde la perspectiva de la ética de las virtudes de Macintyre. Método: investigación cualitativa, del tipo estudio de caso único, englobada en el marco teórico de la ética de las virtudes de Alasdair Macintyre. Participaron del estudio 16 enfermeros que desempeñaban puestos directivos por un período mínimo de seis meses. El esetting era un hospital universitario en Belo Horizonte, Brasil. Los datos fueron recolectados entre agosto y octubre de 2021 a través de entrevistas individuales con guión semiestructurado y análisis de documentos, analizados mediante análisis de contenido según Bardin. Del análisis temático surgieron dos categorías de problemas éticos vinculados a la violación de los valores del cuidado: bienes internos; y vinculado a la ruptura con normas, patrones de comportamiento y relaciones interpersonales: bienes externos. Resultados: el problema ético está presente en el cuidado, en las relaciones y en la institución. Al referirse a los bienes internos de la profesión, los problemas éticos se caracterizan como violación de los valores del cuidado: negación de asistencia; acciones negligentes e imprudentes; o violación de los derechos del profesional, paciente, equipo e institución. Cuando se refiere a bienes externos, tales problemas están vinculados a la interrupción de normas, acciones y comportamientos inapropiados o conductas éticas cuestionadas e irrespetadas por el profesional. Conclusión: las enfermeras directivas entienden los problemas éticos como circunstancias que generan oposición a acciones consideradas correctas y que van en contra de lo propio del enfermero y de su deber, afectando negativamente a los profesionales, la atención al paciente, la institución y el servicio público.

Evaluation of PIK3CA mutations in advanced ER+/HER2-breast cancer in Portugal - U-PIK Project.

Background: Around 40% of ER+/HER2-breast carcinomas (BC) present mutations in the PIK3CA gene. Assessment of PIK3CA mutational status is required to identify patients eligible for treatment with PI3Kα inhibitors, with alpelisib currently the only approved tyrosine kinase inhibitor in this setting. U-PIK project aimed to conduct a ring trial to validate and implement the PIK3CA mutation testing in several Portuguese centers, decentralizing it and optimizing its quality at national level. Methods: Eight Tester centers selected two samples of patients with advanced ER+/HER2- BC and generated eight replicates of each (n = 16). PIK3CA mutational status was assessed in two rounds. Six centers used the cobas® PIK3CA mutation test, and two used PCR and Sanger sequencing. In parallel, two reference centers (IPATIMUP and the Portuguese Institute of Oncology [IPO]-Porto) performed PIK3CA mutation testing by NGS in the two rounds. The quality of molecular reports describing the results was also assessed. Testing results and molecular reports were received and analyzed by U-PIK coordinators: IPATIMUP, IPO-Porto, and IPO-Lisboa. Results: Overall, five centers achieved a concordance rate with NGS results (allele frequency [AF] ≥5%) of 100%, one of 94%, one of 93%, and one of 87.5%, considering the overall performance in the two testing rounds. NGS reassessment of discrepancies in the results of the methods used by the Tester centers and the reference centers identified one probable false positive and two mutations with low AF (1-3%, at the analytical sensitivity threshold), interpreted as subclonal variants with heterogeneous representation in the tissue sections processed by the respective centers. The analysis of molecular reports revealed the need to implement the use of appropriate sequence variant nomenclature with the identification of reference sequences (HGVS-nomenclature) and to state the tumor cell content in each sample. Conclusion: The concordance rates between the method used by each tester center and NGS validate the use of the PIK3CA mutational status test performed at these centers in clinical practice in patients with advanced ER+/HER2- BC.

Lymphocyte Subsets in Cervicovaginal Lavage Specimens of HIV-Infected Women: A Surrogate Risk Marker of HPV-Associated Cervical Lesions.

INTRODUCTION: To better understand the role of mucosa immunity in the development of cervical carcinoma in HIV infection, cervical lymphocyte subsets were characterized in HIV+ and HIV- women, as well as their relation to HPV-associated cervical lesions. METHODS: Eighty-three (52 HIV+, 31 HIV-) cell suspensions of cervicovaginal lavage (CVL) and 52 HIV+ peripheral blood (PB) samples were assessed by flow cytometry to evaluate lymphoid populations. High-risk (HR) HPV was assessed in liquid-based cytology and HIV mRNA in PB in the same patients. RESULTS: Cervical CD4+ T cells and CD4+/CD8+ ratio were decreased (p < 0.0001) and cervical CD8+ T cells were increased (p = 0.0080) in HIV+ women. These patients had lower CD4+ T-cell percentages in CVL compared to PB (p = 0.0257), and the opposite was true for CD8+ T cells (p = 0.0104). They also had a higher prevalence of high-grade squamous intraepithelial lesions (SILs) with an increased prevalence of HR HPV. Cervical CD8+ T cells were increased in HR HPV+ patients (p = 0.0300) and related to higher prevalence of SILs (p = 0.0001). DISCUSSION/CONCLUSION: Cervical lymphoid populations can be characterized by flow cytometry, showing a distinct cervical T-cell compartment in HIV+ women. This may represent a surrogate risk marker of HPV-associated cervical lesions in this population and prompt further research on this subject, contributing to improving patients' management.

No caminho da Estratégia da Saúde da Família: itinerário terapêutico das trabalhadoras rurais durante a pandemia de covid-19 / On the way to the Family Health Strategic: therapeutic program for rural workers during the COVID-19 pandemic

Resumo Este artigo teve como objetivo descrever o itinerário terapêutico das trabalhadoras rurais durante a pandemia de covid-19. Realizou-se um estudo qualitativo por meio da metodologia da história oral temática. Foram realizadas 15 entrevistas com trabalhadoras rurais pertencentes ao território da Estratégia da Saúde da Família (ESF) de um distrito municipal do interior de Minas Gerais. As narrativas foram submetidas à análise de conteúdo proposta por Bardin. Os resultados apontaram duas categorias: "Um caminho a percorrer: desvelando o contexto e a organização da ESF no território"; e "Entre medo e (des)atenção à saúde: visibilidade para as trajetórias das trabalhadoras rurais durante a pandemia de covid-19". Na primeira categoria, revelou-se o itinerário terapêutico das trabalhadoras rurais para a busca de cuidados na ESF do território, bem como a organização do serviço de saúde local. A segunda retratou a intensificação da desatenção à saúde para com as trabalhadoras rurais. Conclui-se que, no itinerário terapêutico das trabalhadoras rurais, a utilização da ESF do território se apresentou como rede preferencial, evidenciando a premência de fortalecimento da APS rural. A pandemia de covid-19 acentuou os dilemas para a busca de cuidados de saúde, revelando a urgência de ações de saúde para esse território.

Abstract This study aimed to describe the therapeutic itinerary of rural female workers during the COVID-19 pandemic. It is a qualitative study using oral history methodology. A total of 15 interviews were carried out with rural female workers belonging to the field of the Family Health Strategy (ESF in Portuguese) of a municipal district in the state of Minas Gerais. The narratives were subjected to content analysis following Bardin. The results pointed to two categories: "A way to go: revealing the context and the organization of ESF in the area;" and "Between fear and (lack of) health assistance: visibility for the trajectories of rural female workers during the COVID-19 pandemic." The first category demonstrated the therapeutic itinerary of rural female workers aiming to access health care in the ESF of their area besides the organization of local health service. The second category illustrated the intensified lack of assistance experienced by rural workers. In conclusion, the use of ESF represented the preferred network in the therapeutic itinerary of rural workers demonstrating the urgent action to strengthen Primary Health Care in rural areas. The COVID-19 pandemic stressed the challenges concerning the search of health assistance showing the urgency of health actions for this territory.

Results of a worldwide survey on the currently used histopathological diagnostic criteria for invasive lobular breast cancer.

Invasive lobular carcinoma (ILC) represents the second most common subtype of breast cancer (BC), accounting for up to 15% of all invasive BC. Loss of cell adhesion due to functional inactivation of E-cadherin is the hallmark of ILC. Although the current world health organization (WHO) classification for diagnosing ILC requires the recognition of the dispersed or linear non-cohesive growth pattern, it is not mandatory to demonstrate E-cadherin loss by immunohistochemistry (IHC). Recent results of central pathology review of two large randomized clinical trials have demonstrated relative overdiagnosis of ILC, as only ~60% of the locally diagnosed ILCs were confirmed by central pathology. To understand the possible underlying reasons of this discrepancy, we undertook a worldwide survey on the current practice of diagnosing BC as ILC. A survey was drafted by a panel of pathologists and researchers from the European lobular breast cancer consortium (ELBCC) using the online tool SurveyMonkey®. Various parameters such as indications for IHC staining, IHC clones, and IHC staining procedures were questioned. Finally, systematic reporting of non-classical ILC variants were also interrogated. This survey was sent out to pathologists worldwide and circulated from December 14, 2020 until July, 1 2021. The results demonstrate that approximately half of the institutions use E-cadherin expression loss by IHC as an ancillary test to diagnose ILC and that there is a great variability in immunostaining protocols. This might cause different staining results and discordant interpretations. As ILC-specific therapeutic and diagnostic avenues are currently explored in the context of clinical trials, it is of importance to improve standardization of histopathologic diagnosis of ILC diagnosis.

Targeted Axillary Dissection after Chemotherapy: Feasibility Study with Clip and Carbon Dye Tattoo - Neotarget Trial.

Background: Axillary staging in patients with complete response after neoadjuvant chemotherapy (NAC) is still controversial. Our objective was to test tattoo alone and subsequentially tattoo plus clip as markers in the targeted axillary dissection of ycN0 patients. Methods: Prospective cohort of cT1-T3, cN1 (proven histologically), M0 patients scheduled to receive NAC. Exclusion criteria were lobular histology, prior axillary surgery, and clinical N2/3. In cohort 1 this positive node (Neotarget node) was tattooed at diagnosis. If ycN0, a targeted axillary dissection was performed. After an interim analysis with negative results we changed the protocol in order to do a double marking procedure (Cohort 2): the positive node was clipped at diagnosis and after NAC a tattoo was done before surgery. Results: Thirteen patients in Cohort 1 and 18 patients in Cohort 2. Failure to identify the Neotarget node with multiple nodes retrieved in 9/13 (69%) of Cohort 1 patients. Also in 5/13 (38%) of Cohort 1 patients and 3/18 (17%) of Cohort 2 there was a failure to clearly identify tattooed nodes. In Cohort 2, clip identification by surgical specimen radiography allowed the identification of the tagged node in 17/18 (94,4%) of cases. The concordance between the clipped node and sentinel nodes was 16/18 (89%). Conclusions: The introduction of double marking by clipping the metastatic node and verifying their removal by surgical specimen radiography, using carbon ink as a tracer, allowed the identification of the metastatic node in 94% of cases, with a simple, reproducible, and easy-to-implement targeted axillary dissection procedure.

Clinical correlation of lymphovascular invasion and Silva pattern of invasion in early-stage endocervical adenocarcinoma: proposed binary Silva classification system.

Silva invasion pattern can help predict lymph node metastasis risk in endocervical adenocarcinoma. We analysed Silva pattern of invasion and lymphovascular invasion to determine associations with clinical outcomes in stage IA and IB1 endocervical adenocarcinomas. International Federation of Gynecology and Obstetrics (FIGO; 2019 classification) stage IA-IB1 endocervical adenocarcinomas from 15 international institutions were examined for Silva pattern, presence of lymphovascular invasion, and other prognostic parameters. Lymph node metastasis status, local/distant recurrences, and survival data were compared using appropriate statistical tests. Of 399 tumours, 152 (38.1%) were stage IA [IA1, 77 (19.3%); IA2, 75 (18.8%)] and 247 (61.9%) were stage IB1. On multivariate analysis, lymphovascular invasion (p=0.008) and Silva pattern (p<0.001) were significant factors when comparing stage IA versus IB1 endocervical adenocarcinomas. Overall survival was significantly associated with lymph node metastasis (p=0.028); recurrence-free survival was significantly associated with lymphovascular invasion (p=0.002) and stage (1B1 versus 1A) (p=0.002). Five and 10 year overall survival and recurrence-free survival rates were similar among Silva pattern A cases and Silva pattern B cases without lymphovascular invasion (p=0.165 and p=0.171, respectively). Silva pattern and lymphovascular invasion are important prognostic factors in stage IA1-IB1 endocervical adenocarcinomas and can supplement 2019 International Federation of Gynecology and Obstetrics staging. Our binary Silva classification system groups patients into low risk (patterns A and B without lymphovascular invasion) and high risk (pattern B with lymphovascular invasion and pattern C) categories.

ABSTRACT Objective: to identify theoretical and empirical subsidies on work environments in primary health care (PHC) in relation to workers' health (preliminary question) that indicate elements related to management (specific question). Methods: six-step Scoping Review with consultation with the subjects, literature search from 2010 to 2019 in six databases and virtual libraries with selection of 21 articles. The complementary stage, consultation, operated a focus group with 14 PHC workers in a municipality in southern Brazil. Results: they were organized into three thematic categories: i) Administrative aspects in the work environment: difficulties related to management; ii) Perceptions about labor relations: barriers between staff and management; and iii) Conflicts in the workplace: coping strategies. Final considerations: bureaucratic and routine PHC issues influence interpersonal relationships and the results achieved, being fundamental for achieving healthy work environments for the actors on the scene. Institutional support, dialogue and the possibility of carrying out work full of meaning and value are workers' rights, reaffirming the promotion of healthy work environments in PHC as an ethical-political priority.

Building Culturally Competent Compassion in Nurses Caring for Vulnerable Populations.

Objective: To understand the process of building culturally competent compassion in nurses who care for vulnerable populations. Method: This is a qualitative study of a "single case study" type, developed with 18 nurses who worked in an emergency care unit in the city of Belo Horizonte, Brazil, between October 2020 and January 2021. Data collection was performed through individual online or one-to-one interviews, following a semi-structured script. Data were treated following thematic content analysis, proposed by Bardin. All ethical precepts were taken into account. Results: After data analysis, the following categories were created: a) Looking within: the recognition of cultural identity; b) Paths to be taken: from the gap to cultural knowledge; c) Attentive listening as essential nursing care; d) Culturally competent compassion as an infinite opportunity for growth. Final considerations: Culturally competent compassion is a subjective, complex, and essential construct in holistic nursing care. When implemented successfully, we gain a significant improvement in the quality of healthcare provided to patients and their families as well as a decrease in social inequality, and the protection of human rights.

Inter-observer agreement for the histological diagnosis of invasive lobular breast carcinoma.

Invasive lobular breast carcinoma (ILC) is the second most common breast carcinoma (BC) subtype and is mainly driven by loss of E-cadherin expression. Correct classification of BC as ILC is important for patient treatment. This study assessed the degree of agreement among pathologists for the diagnosis of ILC. Two sets of hormone receptor (HR)-positive/HER2-negative BCs were independently reviewed by participating pathologists. In set A (61 cases), participants were provided with hematoxylin/eosin (HE)-stained sections. In set B (62 cases), participants were provided with HE-stained sections and E-cadherin immunohistochemistry (IHC). Tumor characteristics were balanced. Participants classified specimens as non-lobular BC versus mixed BC versus ILC. Pairwise inter-observer agreement and agreement with a pre-defined reference diagnosis were determined with Cohen's kappa statistics. Subtype calls were correlated with molecular features, including CDH1/E-cadherin mutation status. Thirty-five pathologists completed both sets, providing 4,305 subtype calls. Pairwise inter-observer agreement was moderate in set A (median κ = 0.58, interquartile range [IQR]: 0.48-0.66) and substantial in set B (median κ = 0.75, IQR: 0.56-0.86, p < 0.001). Agreement with the reference diagnosis was substantial in set A (median κ = 0.67, IQR: 0.57-0.75) and almost perfect in set B (median κ = 0.86, IQR: 0.73-0.93, p < 0.001). The median frequency of CDH1/E-cadherin mutations in specimens classified as ILC was 65% in set A (IQR: 56-72%) and 73% in set B (IQR: 65-75%, p < 0.001). Cases with variable subtype calls included E-cadherin-positive ILCs harboring CDH1 missense mutations, and E-cadherin-negative ILCs with tubular elements and focal P-cadherin expression. ILCs with trabecular growth pattern were often misclassified as non-lobular BC in set A but not in set B. In conclusion, subtyping of BC as ILC achieves almost perfect agreement with a pre-defined reference standard, if assessment is supported by E-cadherin IHC. CDH1 missense mutations associated with preserved E-cadherin protein expression, E- to P-cadherin switching in ILC with tubular elements, and trabecular ILC were identified as potential sources of discordant classification.

Horizontal tumor extent (HZTE) has limited prognostic significance in 2018 FIGO stage I endocervical adenocarcinoma (ECA): a retrospective study of 416 cases.

PURPOSE: The 2018 International Federation of Gynecology and Obstetrics (FIGO) update on cervical cancer staging eliminated horizontal tumor extent (HZTE) as a staging parameter in stage IA (microscopic) disease. We aimed to determine whether HZTE correlates with outcomes in early stage ECAs and FIGO should reinstate HZTE as a staging parameter in futures updates. METHODS: We retrospectively analyzed 416 FIGO 2009 stage I ECAs from 17 institutions and re-assigned stage using FIGO 2018. Correlation between HZTE, overall (OS) and recurrence free survival (RFS) was performed using univariable and multivariable analyses. RESULTS: Re-staging 416 cases resulted in 126 (30.3%) IA and 290 (69.7%) IB cases; 85 (67.5%) IA tumors had HZTE ≤ 7 mm, while 41 (32.5%) were > 7 mm; 32 (11%) IB tumors had HZTE ≤ 7 mm, while 258 (89%) were > 7 mm (p = 0.0001). Four (3.2%) IA (1 IA1, 3 IA2) patients developed recurrence (3 ≤ 7 mm, 1 > 7 mm) compared to 41 (14.1%) IB patients (p = 0.002). Fourteen IB and no IA patients died of disease (8 IB1, 1 ≤ 7 mm). Cox univariate analysis demonstrated that only RFS is significantly influenced by HZTE (p = 0.01), while OS and RFS were not influenced by HZTE on multivariate analysis. CONCLUSION: HZTE has limited prognostic value in early stage ECAs and is only associated with RFS on univariate but not multivariate analysis. HZTE does not improve prognostication of patients with stage I ECAs as per 2018 FIGO staging. Consequently, the rationale to remove this variable from FIGO staging is justified for ECAs.
